Converged ab initio calculations of heavy nuclei

T Miyagi, SR Stroberg, P Navrátil, K Hebeler, JD Holt - Physical Review C, 2022 - APS
We propose a novel storage scheme for three-nucleon (3N) interaction matrix elements
relevant for the normal-ordered two-body approximation used extensively in ab initio …

Nuclear Charge Radii of the Nickel Isotopes

S Malbrunot-Ettenauer, S Kaufmann, S Bacca… - Physical Review Letters, 2022 - APS
Collinear laser spectroscopy is performed on the nickel isotopes Ni 58-68, 70, using a time-
resolved photon counting system. From the measured isotope shifts, nuclear charge radii R …

Surprising Charge-Radius Kink in the Sc Isotopes at

K König, S Fritzsche, G Hagen, JD Holt, A Klose… - Physical Review Letters, 2023 - APS
Charge radii of neutron deficient Sc 40 and Sc 41 nuclei were determined using collinear
laser spectroscopy. With the new data, the chain of Sc charge radii extends below the …
